Multivariate analysis of all descriptive factors was performed to compare pre- and post-interventional HPV and vaccine knowledge.
A hypothetical repeat study found that group sizes from 51 to 1,566 are needed for subgroup analysis, depending on descriptive factor and choice of PRO.
This was to support development of a descriptive human factors model of collaboration – the CoSpaces Collaborative Working Model (CCWM).
Descriptive factors such as period and age at diagnosis, tumour histology, socioeconomic status and gender distributions in relative pairs with lung cancer are presented in Table 2.
These descriptive factors will be measured only at baseline.
Analysis of variance (ANOVA) was used to assess differences in these descriptive factors across exposure regions.
For each patient, staff recorded basic demographic characteristics, as well as occurrence and descriptive factors of each parenteral medication error.
Random forest (RF) variable reduction differs from FA since RF selects important variables without compressing the whole variable set into fewer descriptive factors.
With respect to aetiology, several descriptive factors are highlighted and discussed, including the unexplained male predominance evident for most subtypes across all ages.
